Hi Jeremy,
As far as I know now they are not linked internally as in the past. You
get Design Link which allows your Moldflow to directly read the ProE/Creo
files but you do not fire up Moldflow from within Creo as it was a few
releases back.
It was explained to me that it is just too hard for AutoDesk to keep the
links into ProE/Creo up to date. Not sure when this changed but certainly
true for Moldflow 2013 the present release.
